Autorregresive conditional volatility, skewness and kurtosis [PDF]
This paper proposes a GARCH-type model allowing for time-varying volatility, skewness and kurtosis. The model is estimated assuming a Gram-Charlier series expansion of the normal density function for the error term, which is easier to estimate than the ...

ABSTRACT Circular supply chain management (CSCM) practices are seen as a solution for addressing society's many significant environmental challenges. Although existing studies recognise the importance of reverse engineering in combating poverty, there is limited knowledge about its effectiveness in shaping CSCM practices to address climate change and ...

Continuous drive friction welding is a solid-state welding process that has been experimentally proven to be a fast and reliable method. This is a complex process; deformations in the viscosity of a material alter the friction between the surfaces of the

ABSTRACT The socio‐emotional wealth (SEW) perspective suggests that the specific priorities of a family business may make it more or less inclined to engage in sustainable practices. This paper examines how family business heterogeneity regarding family ownership, financial performance, and family board members affects the sustainability commitment of ...

Kurtosis modelling by means of the J-transformation [PDF]
The H-family of distributions or H-distributions, introduced by Tukey (1960, 1977), are generated by a single transformation of the standard normal distribution and allow for leptokurtosis represented by the parameter h.

ABSTRACT The United States (U.S.) faces challenges in achieving its ambitious net‐zero carbon emissions target by 2050, with current emissions having fallen by less than 1% in 2024. Despite an investment of $500 billion in low‐carbon resources while holding the second‐largest green technology patent portfolio globally, it is further imperative to ...

Kurtosis ordering of the generalized secant hyperbolic distribution: a technical note [PDF]
Two major generalizations of the hyperbolic secant distribution have been proposed in the statistical literature which both introduce an additional parameter that governs the kurtosis of the generalized distribution.

Yield components related to grain yield were severely affected by salinity. For the agronomically important traits, precise phenotyping of crop plants is essential under stress where soil heterogeneity is aggravated for genetic analysis and developing ...
